In order to prolong the service life of the bearings TIMKEN, use process should be pay attention to bearing rust. Commonly used TIMKEN bearing antirust methods are:

1) surface cleaning: cleaning TIMKEN must be based on the nature of the bearing and the conditions at the time, select the appropriate methods. General commonly used a solvent method, chemical cleaning dealing with cleaning method and mechanical cleaning method.

2) surface dry clean available dry after filtering compressed air blow dry, or use 120 ~ 170 ℃ dryer drying, also can use clean dry gauze TIMKEN bearing.

Apply the method of temporary:

1) soaking method: TIMKEN bearing by soaking in the rust of oil, make its surface adhesion on a layer of rust the method of grease. Oil film thickness can control the temperature of the rust or viscosity oil to achieve.

2) brush besmear of: used for not apply for or spraying TIMKEN bearing or special shape of TIMKEN bearing, brush besmear is to pay attention to when do not produce oily-type accumulation, also want to pay attention to prevent leakage coating.

3) spray method: some large TIMKEN bearing can't by soaking method with oil, general use of about 0.7 Mpa pressure filtration of compressed air in the air clean place spraying. Spray method XiShiXing solvent for temporary or temporary thin layer, but must use perfect fire prevention and labor protection measures.

The purity of the bearing of the influence of TIMKEN bearing life is quite large, company was in a special test, the result is the difference of several times and even dozens of times. TIMKEN bearing the higher of cleanness, life is long and so on the test showed that different cleanliness of the ball bearing life of lubricating oil influence. So, improve the purity of the lubricating oil can prolong the life of the bearing, in addition, if oil contain dirt particles in the following 10 control um, bearing life also down times growth.

(1) for the influence of vibration test center of the test results show that the vibration of the serious influence bearing cleanliness level, especially high frequency vibration is more marked. The cleanness of high bearing vibration velocity value low, especially in high frequency band.

(2) the effect of noise on bearing greases on the influence of the noise of the dust done a test, the more dust proof the greater the noise.

(3) the effect of lubricating bearing the cleanness TIMKEN down, not only influence the formation of oil film, can also cause metamorphism and accelerate the grease of aging, which affects the grease lubrication performance decline.
